The National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources such as pipes or man-made ditches that discharge pollutants to surface waters. Industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.
